IoT Monitoring and Telemetry System
Dexfense ReviewedConnected device telemetry architecture with IoT sensors, time-series database, REST API and cloud storage ingestion pipeline.
Overview
Covers an IoT deployment where physical sensors and embedded devices transmit telemetry to a cloud-hosted ingestion layer. Data flows into a time-series database and a NoSQL store, with a REST API exposing dashboards and alerting. Cloud object storage holds raw event data archives. Network firewalls and device certificates authenticate device-to-cloud communication. Logging and DNS support operations and incident response.
Intended for
OT/IoT security engineers, industrial security teams, smart building managers and facility operations teams.
Architecture Assumptions
This template assumes the following conditions. If your environment differs, use Remix to adapt the component selection.
- Devices connect over the internet or a dedicated IoT network segment
- Device identities are based on X.509 certificates or hardware security modules
- Cloud ingestion endpoint is authenticated; unauthenticated device connections are rejected
- Telemetry data is operational; personal data is not collected by sensors
Out of Scope
- ICS/SCADA control-plane and safety systems are explicitly excluded
- Device firmware security and over-the-air update mechanisms are not assessed
- Assumes a standard (not safety-critical) IoT deployment
- Physical security of deployed sensor hardware is not assessed

The full defense plan — mitigations, detection methods, NIST CSF 2.0 mapping and exportable report — is available when you use this architecture in the planner.
Remix copies the components so you can add or remove items before generating your assessment.
Dexfense does not scan your systems. This template identifies threats and controls relevant to this architecture. Product and version validation is still required.
